I thought AOMEI Backupper wouldn't be as much of bloatware as Acronis True Image and I was wrong. I installed it, then uninstalled it, but one driver file remains - ambakdrv.sys. If I remove that file or remove its registry entries opr disable it in Autoruns, then I get a BSOD upon boot: "INACCESSIBLE BOOT DEVICE". It is set to load during boot. Process Hacker reports it as a "Boot Start" driver. It cannot be stopped from running once OS is loaded, but it can be removed in Safe Mode or with Unlocker. Once removed, the "INACCESSIBLE BOOT DEVICE" BSOD appears during OS booting after a restart. Removing it pretty much breaks the OS. The same thing happens if I search for that driver in registry and remove entries with "ambakdrv" in them. I use RegScanner for that. How can I get rid of that driver then? What makes the OS require that file for booting?
